Characteristic parameter analysis of boilover fires

Boilover fires in large-scale oil storage tanks can lead to significant losses, and the damage degree of boilover fires is closely related to combustion characteristic parameters. A series of small-scale boilover experiments were carried out, and the variety regulation of parameters including burning velocity (linear burning rate and mass burning rate)， heat release rate, flame temperature, radiation and flame height in the combustions of mixed crude oil and mixed oil(kerosene and lubrication oil) during and before boilover were investigated. The experimental results show that these parameters of boilover mutate, so that the values of burning velocity, heat release rate and radiation during boilover can be several times and even dozens of times of those mean values. Based on the qualitative and quantitative analysis, the reason for the mutation was discussed. which can provide a theoretical basis for controlling the loss of boilover during full-scale oil tank fires.
